Why would you want to do that?
A common tool for measuring the effectiveness of your emails is to send half the recipients the mail in 'Format A' and send the other half the 'Format B' version of the same message and then compare click-throughs.
There needs to be some degree of randomness in the selection so you couldn't, for example, use sign-up date to split the list in two (or more). Nor could you, for this purpose, use the demographic fields.
You could though use even and odd Contact ID to split the group into two and then add the odd ones to Group A and the others to Group B

Has anybody any ideas how to achieve this in practice?

how about using a custom search, maybe this one:

CRM/Contact/Form/Search/Custom/RandomSegment.php

would be even more powerful if we can send in some arguments from the mailing to the custom search (and say things like: gimme 20% of the contacts, but dont include contacts who've already recd mailings A, B, C)
