Apologies for the delay in replying.

We are currently reviewing CCP4 licensing and things
may change in the medium future. In particular, we
need to agree an explicit policy for web services, as
they become more common.

In the mean time, we'd ask that you set up some 
system to check that users (whether academic or commercial)
have a CCP4 licence.

For example, the TB Consortium Bias Removal Server
has a CCP4 agreement page, see tuna.tamu.edu/ccp4agreement.html
When users click Agree, we get sent an email, so we can
check licensing. 

Something along these lines would be acceptable to us.
Let us know what you set up, and we'll give it a quick
check.

Regards
Martyn
