We have seen this debate here in Alaska with the '"diehard" (read 
this also as the super pro-CW) ham disliking anything dealing with 
marriage between the Internet and ham radio.  Remote base stations 
are a separate case in my opinion.  Hams have constructed remote base 
stations using all sort of linking technology.  I am fine with 
this.  I am an amateur radio astronomer and quite familiar with some 
of the Internet remote telescopes.  Its a great way for folks to 
participate in activity using equipment beyond their means.

So I have no problem with remote bases linked by IRLB, echolink, or 
like technology.  As long as any records, contest entry reflects the 
actual radio transmitter QTH.

How about a Lunar Remote Base?
