I simply don't have time to do any big changes to LiVES. By the time I 
get the laptop, I will have about two weeks to play with it before I fly 
to Brazil for FISL. I will be back in Europe in June, but then it looks 
like I will have to get a full time job to support myself. (Despite four 
years of trying, I have been unable to find anyone interested in 
sponsoring my work on LiVES/videojack/livido, etc). I even had to sell 
my house last year so I could continue working on my FOSS projects. 
Perhaps in 2008 I might be able to continue, there is a small 
possibility of some LiVES funding then from a university in Brazil.

So basically, unless it works "out of the box", or a miracle happens, 
it's probably not going to be possible for me to port LiVES to the OLPC 
this year.
