computer-idiot question regarding this new CD key check thingy in 2.11

[tinkthank]

Sorry if this is stupid, but:

Will this new patch prevent me from playing domII on 2 different machines (as I have been doing so far)? I commute between two cities and have it installed on both. Currently in city A and have 2.11 installed, when I update to 2.11 in city B (which is installed with the same CD key of course) will it cause problems?
thanks in advance

EDIT: sorry, one Last thing: since it apparently "calls" "home", whatever that means, does it mean I need a modem connection up and running, even when playing SP? Does this cost extra phone bill money?
