SAP PI as JMS Provider

HI Experts,

We want to read the data from Webshere MQ Queue using sender JMS adapter and we want use SAP PI as JMS provider and place the data in SAP PI JMS queue using receiver JMS adapter based on below Welliam Li blog

http://scn.sap.com/people/william.li/blog/2006/11/13/how-to-use-saps-webas-j2ees-jms-queue-in-exchange-infrastructure

1)So can we use SAP PI as JMS provider??

2) can we use this for large volumes (we expecting 2 million messages per day)

3) Can we monitor JMS Queue (as far as i know there is no monitoring for JMS Queue)

Please suggest your thoughts.
