Hmm...
Lets see:

1. POSIX (or at least SuS v3) does not gaurentee the existence of /dev/shm, 
or that if it does exist, that it can be be read as a block device, or that 
if it can, it has a file system on it.
2. Neither does FHS.
3. The Linux 2.6 device list states that as of now, if /dev/shm exists it 
should have a tmpfs filesystem. But makes no guarentees that it exists, or 
that it will remain a filesystem


So AIUI:
1. It exists only on Linux-based OS's
2. There is no gaurentee that it will continue to be there at all
3. There is no guareteee that it will remain a filesystem in the future even 
if it is there.
4. There is no gaurentee that it exists at all.

Sounds it sounds to me like it is a bad idea to use it.
