Signing is easy. The difficult part is 1) to create a system in which 
you can prove that the key really belongs to the user specified in the 
userID 2) to make contracts singed by verified key legally recognizable 
and enforceable.
We are working on 1) and 2)

For 1) I mean the case when users has signed a document or contract, and 
after that this user claims that the signature was not made by his key.
In such case, I think signing keys on 'key signing party' is not 
reliable. There must be a known key verification procedure, and a 
permanent repository of information and documents that were used to 
verify the key.

And we actually not sign keys. From two reasons:
a. If you automatically trust the signing key, compromising the signing 
key breaks the entire system.
b. In many countries, generating or signing cryptographic keys requires 
a license. We create a system that should work the same way and legally 
in all countries. And we do not sign key certificates. We only attach to 
them information about the owner of the key, which the user manually 
checks before adding this certificate to his list of trusted certificates.
