Hi Sylvain

Ill try to explain a bit about how biblio, biblioitems and items fit 
together.

Having a biblio with more than one type is perfectly fine, thats what 
its designed for.
Using my favourite example
The Two Towers
http://opac.library.org.nz/cgi-bin/koha/opac-detail.pl?bib=4069

This has 1 biblio, 7 biblioitems and 9 items.

This allows ppl to reserve just the biblioitem they want, eg video.
 From your email it doesnt sound like the itemtypes being part of the 
biblioitem is the problem. It sounds like you need a rule when defining 
a borrower category, that specifies the maximum number of items that 
borrower can borrow?

It sounds like it isnt to do with itemtypes, but more that there isnt a 
way to tell Koha, only let this borrower have a total of 12 items out at 
any time. Is that right?
