I am trying to use parfeval to do a webread on a background pool and it responds with the message...
Invalid default value for property 'UserAgent' in class 'weboptions':Use of function version is not supported on a thread-based worker. Use alternatives supported on the background pool.
which I assume means I can't use webread with the background pool.
is there another way to do this?

Unfortunately, as you suspect, right now the only way to do this is to use a process pool via parpool('local') or similar.

As Edric suggests, use a local parallel pool.
pool = parpool("local",1);
f = pool.parfeval(@webread,1,'http://www.mathworks.com');
f.wait
size(f.fetchOutputs)
