So, it's official

Today I got an email from Google about Wave. The end is near :-(

The message was:

"Dear Wavers,

 More than a year ago, we  announced that Google Wave would no longer be developed as a separate product. At the time, we committed to maintaining the site at least through to the end of 2010. Today, we are sharing the specific dates for ending this maintenance period and shutting down Wave. As of January 31, 2012, all waves will be read-only, and the Wave service will be turned off on April 30, 2012. You will be able to continue exporting individual waves using the existing PDF export feature until the Google Wave service is turned off. We encourage you to export any important data before April 30, 2012. 

 If you would like to continue using Wave, there are a number of open source projects, including Apache Wave. There is also an open source project called Walkaround that includes an experimental feature that lets you import all your Waves from Google. This feature will also work until the Wave service is turned off on April 30, 2012. 

 For more details, please see our help center.

 Yours sincerely,

 The Wave Team"

Any good alternatives to Google Wave? It's opensource maybe someone will run it or already runs it? Please leave a comment if you know something.

UPDATE:

I've found that actually something is working and it has strong number of supporters. On Apache Wave project site http://incubator.apache.org/wave/ there is info about their project "Wave in a Box". This will be easy to run on you Linux version of Wave, that utilizes other Apache's software. Apparently Google Wave was written is such way that it was not compatible with Linux. Right now guys are migrating stuff.

There are even working Wave servers right now. Look at http://waveinabox.net, in my opinion it works pretty good.
