Not at all!

We often use setups similar to the one Frank described (external L4 task doing real-time work, L4Linux runs a timesharing load) for research purposes.
I am not aware of anyone who used L4Linux clients for real-time work, but the idea is interesting. I see that L4Linux clients are easier to develop and debug. However, Frank recently finished an L4-task loader for L4Linux that regains some of Linux' convenience for L4 development.
- Is L4-Linux going to keep up with the revisions of Linux in the
future?
We certainly plan keeping L4Linux up-to-date, but I cannot make any promises. It's a matter of demand (both by ourselves and by others) and resources.

Hello,
The same apology again for my 10 days too late reply.

I really understand what you mean.

I'm glad to hear you say so.

There is more to the reason of my persistence in doing "L4Linux clients for real-time work". My application, actually not my application but a rather complex application shared by lots of institutions for large scaled experimental physics, requires real-time tasks and non-real-time tasks to share the same address space. The application is named as Experimental Physics and Industrial Control Systems (EPICS). Please take a look at http://www.aps.anl.gov/epics/ if it could interest you.

I hope the "demand" increases more and more because I think L4Linux is attractive from the both points of views, OS and application.
