Using VSeWSS relieves you from custom intall.bat!
If you like to be more productive in WSS development, you can always use Visual Studio Extensions for Windows SharePoint Services 3.0.
Visual Studio 2005 -> VseWSS 1.1
Visual Studio 2008 -> VseWSS 1.2
Then, set the "Start Browser with URL" to your Web App URL. With that, you can enjoy the Deply (solution packaging, deployment, and activation) funtionalities provided by the extensions.
