It would be good to discuss what the options are here. The hardware can probably not be described as inexpensive, but it's also quite capable so not much is needed. Would trying to acquire a 2U rack mount server, and host it in a proper data centre be feasible? Because of both electricity usage and heat generation, it's going to be more difficult to host residentially I think. --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQKlBAEBCgCPFiEEPonu50WOcg2XVOCyXiijOwuE9XcFAmDNO3lfFIAAAAAALgAo aXNzdWVyLWZwckBub3RhdGlvbnMub3BlbnBncC5maWZ0aGhvcnNlbWFuLm5ldDNF ODlFRUU3NDU4RTcyMEQ5NzU0RTBCMjVFMjhBMzNCMEI4NEY1NzcRHG1haWxAY2Jh aW5lcy5uZXQACgkQXiijOwuE9XdkUBAAlJX/0oLkKJCcSuOInExDn7cOxIwG7Tpg xjhcM74AvZ1gW3eXfYSWER92gk+GMODVGi4W6K/TI+CytvXxI5zRcXFPl6zoqCCm lYMflSq4K3h7IY2LvBgBYV0IX2TRyMGZT1Ec0JNHFFKSPsGa89eAWtNmgLrn/D/P TJujcUUbFADMuQklD9iUVMqYDsmqYJQKWkkOoNe3sINF5qGmauCvAmp149i0Hu+i CEjiBeIFe6ctLh1m1CmiCsJZRXo9GIMVDKa7RZ3ytcdd9PiUL9wOtVD0a2WcUmn6 0K/0+sZkcKl9rIJF+A1kcPoJ+WngiYaVlqLvYY3w0avpaxswuDS4uAA1t6uo+qZV MWOG2tMHulxKV5s29JlZpvgCfDMA7SplVGvfQMfCtBpXmL4lpEX9TYrM95A58fqg ++ny03bxKtMjd1p+KbFBXUe7bFETUiLKPuGsnwwItSRx8e1SwTdPul1RiHAUo+cB d5OkZtPI+gFPHXHCdmddH7HDNwFubeTwNXVzzx8tWSAM2j9DG0MgAd5vVKBzh5/7 g9jF4XTzbc+A0k/3mWpd8gjmn6Kw/Rjmc2nXYd6OATRDWQEQhc0RfmgbLpdB+ieV 9XophU3G99pGD+7/neyzJ80pQjjlo9kdy7be7FcW+uqRY8kHVI+JufoQXbtcIRTj LPr/vv9r4x0= =X9zx -----END PGP SIGNATURE----- --=-=-=--
