Can a TupleSpace be mirrored to a secondary server in way that the  
clients accessing it can fail over to it in the event of a server  
failure?

I understand that a TupleSpace can provide fault tolerance, I just can’t  
find any documentation to that fact in the Ruby implementation.

Thanks!

Don

Here’s a start:

This just creates a slave, you’d have to add the switching logic and  
re-master stuff yourself. I don’t know what’ll happen if you add  
tuples with expiry times or renewers, buyer beware.

Thanks Eric! I’ll have a look-see. Hopefully I’m not getting in over my  
head. 😉
