As long as there's no e.g. file-sharing we won't run afoul of the JANET or OUCS rules. The only potential stumbling block is college network administrators and their internal firewalls, but there's amount of discrepancy between colleges and as you say, there's always the option of tunnelling out over e.g. ssh. (I wouldn't be on IRC without it.)
Universities have lots of experience with conference accommodation, I'm sure they have systems in place for giving conference goers internet access, it can't be an unusual request.
