I have yet to see a documented case of collision, but yes it is possible, I
don't see that as a big problem.
All that needs is to lodge the public key to open an account.
To do any transaction would just require signing a generated transaction
request.
Keyid should be enough for an account identifier, but to be totally (well
within the bounds of probability less than that required for 6 impossible
things before breakfast) safe you could use the complete public key of the
recipient to make the transfer.
keyid risk is 1 in 2^32 (almost 1 in 4.3 billion, but I suppose it could be
manipulated)
this risk could be mitigated by displaying fingerprint of that key lodged
with the service.
fingerprint risk is 1 in 2^160 (possibly a bit worse than that, not too sure
of all the inner workings)
Of course there would always be the risk of a total key collision but that
is unthinkable.
