well, sure, i agree in principle ... if arXiv and similar projects agree 
to bunch of all physics into a single category and use google for 
searching, with no browsing capabilities, it wouldnt be a problem at all.

similarly, if we grouped together computer science, electrical 
engineering and information systems, that would be ok for gross-level 
interoperability ... once again, assuming searching is the only service 
required. frankfully, i think this is a little simplistic and assumes 
digital libraries are no more than submission+search systems.

[aside: why does eprints support browsing by catgeories ?]

besides, who decides what constitutes a discipline anyway ? has anyone 
ever been able to decide if computer science is engineering or science ?

i think we have more questions than answers here and it isnt as simple 
as you point out or we wouldnt even be discussing this :)
