Hi! Right now I'm using it with s-2vcpu-4gb droplet and yesterday I had a meeting with 10 people without any problem. The CPU were at 26% on average, the inbound traffic at 13 Mbps and the outbound 40. Disk usage were negligible. Today I'm going to try with even smaller droplets to see how far I can push it :)

Keep in mind that the selected droplet costs around $0.030 per hour so that's $20 per month. The good part is you can tear this setup down very easily, so you can save money whenever you're not using it.
