Full support for PostgreSQL would be the other big feature.
We're just starting the testing process for the first release (English only) of dotLRN for Oracle and Postgres if you want to take part.
New functionality will be made available in interim releases immediately following dotLRN v1.0. Some are definite (events module, wimpy point); others very likely (blogger). dotLRN v2.0 will have i18n support and much more. Carl Blesius is working on a map and we hope to make that available very soon.
Here is the UNOFFICIAL rough draft of the development map I used for some grant applications. It is old and pretty superficial, but it should help give you an idea of where we are at right now. As soon as 1.0 is out we can start to solidify what is next (the 1.1 part of the document) and create an official dotLRN roadmap that covers the next couple of months.
