Agree.  The DVAP is the ultimate in portability, and brings the best 
of both worlds - Local Internet connectivity and the portability of 
your D-STAR radio.  The hotspot, OTOH isn't as portable, but it 
allows for _much_ greater range, so you can offer services to local hams.

And don't forget to configure and align the radio!  Tx modulation 
level, in particular, is quite critical when setting up a 
hotspot.  The use of test equipment is highly recommended (that said, 
I did mine by ear and got it right).

I don't own a DVAP, but it is on my wish list, because the problem 
space it deals with is different enough to the hotspot to warrant the 
expense, even though both actually do more or less the same 
thing.  I'd use the DVAP for travelling and nets where there was no 
local interest, leaving the hotspot free for local users to enjoy.
