Those machines are called in Polish "Łunochody" (singular: łunochod), like that Russian moon rover (http://en.wikipedia.org/wiki/Lunokhod_programme) although the name has been Polonized.
There are even races of such machines organized.

I did not mean lend, but give/sell. I only give away CDs I do not need/want anymore, so I do not have mp3 from them.
Nitcheplayer is right that lending CD is problematic. I have not written about lending CD :D, though.
OK you are right, it is hard to solve this problem (and is one of purposes for corporations' paranoia).
I never rip CDs borrowed from others and I hope others do not do this when I lend my CD to them. Probably when I lend CD I should not listen to music ripped from it :D.
Licenses should be here more elastic.
There ate a lot of problems to be solved in licenses, but it is just matter of good will and honesty of corporations and customers.

When you buy music/movie, you do not really buy something physical, but rather some rights for personal usage like: listening, viewing, mixing. Of course you pay for some quality, so if You pay for 128kbit mp3, You may not own 192bit (it would be like paying for Smart and demanding Ferrari), until you pay for it (though you may use lower quality).
Of course licenses are trying to limit your rights as much as possible (CD copy->forbidden, mixing music with movie from your grandmas birthday party->forbidden, etc), so that you would have to buy more items, that is why you may not make personal copy of CD to listen in your car, which is stupid, because you have payed for rights to listen and CD is only carrier for object of your rights.

When you pay for Book or CD/DVD, you get "official carrier" of bought media (paper, cd) which is also prof of your license. This is quite cool, because carrier and license are bound together and can be easily passed to another person (given, sold, exchanged). I love this old model because: my parents gave me a lot of old books, I got a lot of old vinyl records from may grandparents and I spend a lot of time with my father, searching for old books through the second hand market.

In new digital model DRM is prof of your license (rights?) and quality of media, that is bound to carrier: a file. In case of music this model seems to be nice, you do not need to buy entire album. There is problem with that media, file does not physically exist like CD or paper, so there is no original carrier of your license (personally copied CD and book does not look original, but files look the same bit-to-bit).

When you give book or CD to another person, you are also giving away your license. But when you are giving file (mp3 for example) you could keep copy and license for yourself and new owner would not know, DRM tries to prevent this.
I do not like this model because I know it would not be possible for me to sell or give away DRMed files (e-books, music) to other people when I no longer need/want them, what I can easily do with non-e media like paper.
Additional problem for me is that I use *nix systems mostly (Windows for some development and gaming only) and DRM (in my country music is mostly sold with MS DRM) would not allow me playing music while I work, etc.

I have written, that when music is bought, in reality right to listen is bought... DRM cripples even this right, because it limits it to: certain software; certain hardware; may require network connection; and may be canceled when license provider will stop to support current technology.

While media like CD or paper have some value and can be sold (I mean original of course), DRMed files have no value (except personal) because they can not be sold.

Thats why I do not support DRM, I will keep on buying CDs and DVDs (though the other one has some DRM anyway, but I have no choice here), I will buy paper books instead of e-books and wait for lawyers and corporations to get sane and stop believing that each of their clients is trying to rip them off.
I do hope that Europe, where I do live, would drop DRM or disallow it as anti-customer technology.
