Hell Surabh,
yes it is the same Frontendserver and users should start with the mentioned URL. The app is also available in the Launchpad.
Regarding possibility - I think that it should be. At the end of the day an intent is resolved to a URL. This is based on LPD_CUST, Launchpad designer, etc. So why shouldn't it be possible to do that for the Launchpad? Maybe just the URL you are referring to. But in a more flexible way.
I feel a little supoort on that idea from http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/907ae317-cb47-3210-9bba-e1b5e70e5c79?QuickLink=index&overridelayout=true&59575491523067. In that there is a paragraph "Best Practices" mentioning a launchpad intent.

Meinrad
