Outrigger is a complete implementation of the JavaSpaces spec.

Yes though some implementations may provide more support for JINI 2.0
than others (not entirely sure what the state of play is here).  Note
that JINI 2.0 provides backward compatibility so it's possible to mix
JINI 1.x and 2.x services.

However, 1.x services won't provide much in the way of security unless
the author has done something non-standard for themselves (this is
because JINI 1.x provides no explicit security support).

The license is the ALv2 (Apache License version 2.0) which, in most
cases, allows you to do as you wish but I would encourage you to read
and understand the license for yourself and make sure your commercial
intentions do not conflict with it.

I don't think you'll need to buy a license but you must make sure that
you comply with it's terms.
