No, but since it's a single license intended for a single machine, simultaneous
usage would probably violate the license agreement.

No, that won't happen, either.  If the two licenses were on the same system, it
would not allow you to run more copies of Mathematica.  I.e., you're limited to
two copies running simultaneously, regardless of what version they are.  But
it's not going to go out and sniff the network for other copies.

Once version 8 is activated on the new system, you should be able to run v7 on
the new system without a problem (i.e., v7 will be enabled by the v8
activation).  I'd suggest using this route for migration rather than keeping v7
on one system and v8 on the other.  You won't accidentally violate the license
agreement, and it should just work.
