Has anyone had experience with sharing the crystal over multiple LPC21xx 
oscillators? I have a design where I am multidropping 2101s together 
over the SPI bus (slave listen, master to talk). It seems a bit over the 
top to have a separate crystal for each chip though and I am looking at 
running the XTAL out from one chip to the XTAL in of another and so on 
(to reduce loading). Of course, the line length will be short and shielded.

Has anyone actually done this?
Are there problems that you may have actually experienced?
(Notice the "actually" :) )
Have you perhaps had problems with similar arrangements?

I have done this with other types of chips before and I can see no 
problem with doing the same with the LPC21xx. Oscillator output levels 
look fine and are in the 0.3 to 1.6V range which on the oscillator's 
1.8V unbuffered gate indicates strong drive.
