You audit on two fronts, look at the systems for the controling
application<s> required to use it and you look for connections to their
server<s>:

Non-authoritative answer:
Name:    www.gotomypc.com
Address:  63.251.224.169


Non-authoritative answer:
Name:    gotomypc.com
Address:  63.251.224.169

And if one wants to be a tad more careful in what they block perhaps a
whole class C:

[jengate.thur.de]
Process query: '63.251.224.169'
Query recognized as IP.
Querying whois.arin.net:43 with whois.

InterNAP Network Services (NETBLK-NETBLK-PNAP-11-99) NETBLK-PNAP-11-99
                                                   63.251.0.0 -
63.251.255.255
Expertcity.com (NETBLK-PNAP-SFJ-EXPERT-RM-01) PNAP-SFJ-EXPERT-RM-01
                                                 63.251.224.0 -
63.251.224.255

Admittedly I have not investigated any more then a mild look to determine
if all their server<s> are contained within this netblock.  But, this is
not unmanageable.  And certainly should be covered in the security policy
and the corporate AUP.

Thanks,

Has anybody dealt with the services from https://www.gotomypc.com it
seems to allow end users to completely circumvent an existing network
security infrastructure.

The user signs up with gotomypc and establishes a out bound connection
through the firewall to a go to my pc server, then there server listens
for a connection that is connected to your internal network
and the scariest thing is that the listining ports for inbound
connections are on a gotomypcserver so how would you even audit?.
