I just committed the last bit for re-enabling SRV for hkp (which gives  
us hkps as well).  Sorry for the delay.  I just started a new job, and  
it's been a wee bit busy around here.

If anyone who is tracking the 1.4 branch from svn wants to give it a  
whirl (especially for hkps), please do, and let me know how it works  
for you.  Once I get a response or two, I'll integrate it over to the  
2.0 branch.
