That's very interesting. Some questions:

* how are multiple classes merged?
* can classes be assigned by other means besides regexp?
* why not an obarray?
* a macro `with-process-classes' would be nice

It seems like these are process-local variables, in the sense that you
may want them per address@hidden:port combination (or other process
parameters), not just hostname. Thus it may be better to make this a
process-level facility.

I think the GnuTLS code could use this facility as well. Right now
gnutls.el has ad-hoc facilities for this purpose, if I understand you
