Via Infoworld:

Six Apart expects Movable Type Enterprise to offer an attractive way for companies to improve internal communications and knowledge sharing. Its low cost means the offering could replace other software tools designed to deliver similar collaboration and content-management benefits, Six Apart said.

At the low end, a license costs $4,000 with the option of an additional $2,000 yearly fee for customer support. The support fee includes product updates and a two-hour response time to questions.

The Six Apart press release lists features, of which I'll highlight the more interesting:

• LDAP authentication

• Oracle 10g database support

• Cross-blog publishing and aggregation tools

• Powerful anti-spam protection with solid feedback management tools

• Customizable email integration

The Infoworld article mentions a few other competitors in this space: iUpload and Near-Time Inc.
