I think different people will try different things, as they are inspired, in repsonse to the environment they find themselves in. I remember that when I lived on Maui, Siddhasvarupa's folks had a big kirtan hall they met at for kirtans and classes. when the devotees asked if we would bring our Deities up there, Siddha asked us to bring them back to our house and suggested that anyone who wanted to join us in worshipping them come down to our house (we lived on the same property--6 acres on Peahi Road, just up the road from what had been The Banana Patch commune in the late '60s). Here on the Big Island, his disciple Garuda das has a kirtan hall with an altar, with big pictures of Lord Chaitanya and Lord Nityananda. Garuda's wife does arati as part of their programs.

I think that whatever helps others become more Krishna conscious and doesn't flagrantly flout the guidelines of bhakti would be considered bonafide. In Jaiva Dharma, the babajis at Godruma just get together under nice trees for hearing and chanting.

I remember hearing that, before he even spent any time with devotees, Tripurari Maharaja would have Krishna Book classes at his place. When the devotees came up there and found him, they brought him back to LA, where he was inititated and engaged in distributing books as no one else had.
