Thank you for first response. It could be a bad idea as you say. There is no doubt I like TCL a lot, particularly modularity and architecture. This was a fantastic idea and I think that at this point none other matches dexterity of concept and architecture. That is exactly why this idea should be extended to other systems and BSD is the first one that comes to my mind as the biggest impact after Linux.
The importance of this would be very significant IMHO. Let us consoder this: Linux is great as opensource, etc. The problem that developed over time is that it is terribly fragmented, poluted with garbage and most Linux became horibly bloated. Even TCL, fantastic as it is, it is among hundreds of distributions and it is hard for many to recognize it's due value... BSD would open another dimension for this architecture. Let us also consider the fact that TCL has matured at this point. New software will be ported, etc. and will be more and more usefull. TCL will continue to evolve but at this stage of maturity its evolution will be quantitative. Similar such earthshaking architectural chage could be brought to BSD and thanks to less fragmentation of the landscape and rock-solid kernel, security including, this might be of significant value for practical implementations.
