Currently following modules are available:
- r.stream.order: to calculate Strahler, Horton, Shreve and main stream (Hack) ordering. That module is almost ready to use
- r.stream.basins: calculate basins according users input. Read more on web page
- r.stream.distance: calculate downslope distance path and elevation above to streams/outlets. That module is in early development stage, but works, and results seems good. But it may will change in the feature.
-r.streams.stats: calculate hortonian statistics is not avilable: maybe in next few days.
All three modules works fine on small dems (up to 20 millions cells). Only on powerful machines with at least 2-4GB RAM they handle avarage dems (up to 120 M cells). I have no information about largers dems (over 100M cells because I haven't so).
Till I finish my work modules are available only from my web page. After I will absolutely sure that everything is OK, add vector capabilities and solve problems with massive dems (for LIDAR puropse) I will try to add them to GRASS add-ons.
Excellent! Those are fantastic. Thanks for the contribution. We are working on some stream assessments, and I hope to be able to get time to try these modules. I will be sure to provide feedback.

I would suggest to you to put your modules to the GRASS Addons [1].
Then the modules can be downloaded & installed easily by g.extension.
As soon as will be finished. Because only r.stream.order is almost finished I plan do keep developing them. For that I shall have write access to Add-ons svn. But I do not want have it. I modules will be ready for add-ons in next few weeks. Than it will be available for all users and I will start to create next version.
