Real-Time does mean the system reacts in time. There is nothing a software can do if the hardware is not meeting your requirements of beeing in time. Having reliable 0.5 ms real-time is e.g. for us absolutely real-time and we chose carefully our hardware components that this will never be exceeded. For us Xenomai and RTCAN on a MPC5200B platform do a good job. I cannot imagine that the developers of > rt-can overlooked this.

Parallel port CANS are certainly much slower than e.g. PCI adapters. On a Laptop you have the possibility to add e.g. PCCARD CAN. But before purchasing I would check how these are supported and which typical access times you can expect. USB CAN is certainly even slower, so this will be no option.
