Could anyone help me figure out if it is possible to sign multiple 
interrupt sources with same interupt vector:
ie: 
po.3 and p0.14 for Eint1, so EINT1 will respond for any level changes 
from both p0.3 and p0.14.

Yes, point them to the same ISR.  Since you won't be able to get the 
same priority for both, make sure the ISR is reentrant.

How do you make an ISR reentrant?

Carefully :-) Same as usual. You will have to reenable interrupt. Make sure 
not to use global data etc. Not particularly tricky to make it reentrant. 
The trick is not to die from too many nested interrupts and blow away your 
stack etc.
