OT - BASH question?

Does anyone know of a GOOD bash list? If yes - I'll go there.
The following works:
while read line; do
...
...
done < somefile
...
...
How would one go about doing something similar replacing the file
redirection with the output of a command? Before you say pipe it, that
doesn't work because the pipe starts a subprocess and anything done
inside the while loop is lost to the rest of the original process.
i.e.
ps -eo "%p" | while read line; do
... # anything done here is
... # lost to the original process
done
... # Code here can't use anything
... # done inside the while loop
Suggestions?
