A transparent python library for symmetrical remote procedure calls, clustering and distributed-computing.

RPyC (IPA: /ɑɹ paɪ siː/, pronounced like are-pie-see), or Remote Python Call, is a transparent python library for symmetrical remote procedure calls, clustering and distributed-computing. RPyC makes use of object-proxying, a technique that employs python’s dynamic nature, to overcome the physical boundaries between processes and computers, so that remote objects can be manipulated as if they were local.

python RPyC user count

I wish to use RPyC to provide an API for a hardware board as a service. The board can only cater for a single user at a time. Is there any way I can get RPyC to enforce that only a single user can get access at a time?
