Playing multiple SnG's

[Savo]

Thanks in advance for any help on this.
Having recently started to log my results on low cost (5+1 and 10+1) No-limit SnG's, i'm considering starting to play on more than one table at a time. Are there any specific techniques that you can use in order to play this way while following the games? Obviously this also applies to cash tables. I think this is the one area of the game that I haven't really seen discussed, yet is, I guess, a major benefit of playing online. Is it just a case of taking each hand you play in isolation?
