A couple notes about ColdFusion MX 7 licensing for the Free Developer's Edition and the Standard Edition.

The Free Developer's Edition of ColdFusion MX 7 now permits you to access the server from localhost plus 2 other client addresses. This is a change from earlier versions of ColdFusion Developer Edition which restricted the server to handling requests for localhost plus just 1 other client.

As previously blogged, ColdFusion MX 6.x EULA permitted users to install the Standard Edition on up to 8 cpus, although it would be difficult to know that unless you either read the EULA or my blog entry. ColdFusion MX 7 has a new EULA permitting the installation of the Standard Edition on up to 2 CPUs only, with a maximum of 1 machine per 1 license. If you took advantage of this licensing loophole in CFMX 6.x, then it may cost a bit more to upgrade those to CFMX 7.
