Diffie-Hellman Key Generation

Does anyone know of software available outside the US for generating
large (1024-bit or more) Diffie-Hellman keys ? The default key for CTCP
is only 512 bits, and I'd like to be able to give out some larger keys
(e.g. 1024 and 2048 bits) so that people have a choice of the level of
security that they want to use.
Alternatively, does anyone have any pre-generated large keys that I can
put in there ?
Finally, I'm basing this on comments in 'Applied Cryptography' that D-H
keys should be at least 512 bits and preferably 1024. How does the
difficulty of breaking a D-H exchange with a 512 bit key compare to
breaking a 512 bit RSA key ?
