[ros-users] Topic Relaying between two different ROS masters

[Tully Foote]

Hi Jan et al,

For awareness there's actually several multimaster implementations and a
SIG for discussing them as well: http://wiki.ros.org/sig/Multimaster

If anyone would like more info on any of these, I suggest you poke around
on that sig. The mailing list is: http://wiki.ros.org/sig/Multimaster

Cheers,
Tully
