I haven't really done any kernel development, but from what I've seen the technical issues are mostly eliminating #ifdef'd compatibility code and getting the rest of the code up to kernel standards (better use of sysfs etc.). Zaptel cards are capable of providing pretty precise timing. The current Zaptel drivers expose that through a non-standard interface at the moment - it'd be nice to switch that to using the high resolution timer support in the rest of the kernel. There are also a couple of drivers that use some code / firmware from Octasic. The Octasic code is GPLv2 (or later) as far as I can see. Don't know about licensing for the Octasic or the Digium firmware though. Politically, it would be nice if Digium would at least sign off on the idea if they don't/can't contribute any developer resources at this time. Digium actively develops the Zaptel drivers, at least fixing bugs and adding support for new hardware they have developed. I haven't seen any work from them (publically at least) on restructuring the code that would make it more acceptable for inclusion in the kernel.
