Not yet available, and unless a shed load more streak's are sold it's not going to be, along with all the other accessories we'd like to see. This of course is not helped by the FUD (fear, uncertainty and doubt) spread by things like the streak 5 mark 2, software upgrade path 2.x or 3.x etc..
For waterproofing there are some waterproof bags made for sunbathers to protect devices from sand and water. You won't be able to use the touchscreen though. Would work for listening to music, GPS, stuff you can start and leave.
If the otterbox is not strong enough then you're on your own. You could carve a cover out of some high impact dense foam material. How pretty it ends up would be down to your skills.
