I suppose it depends what you mean by 'presence of others' and also the medium?
I've soloed routes on crags with no one around, and I've also soloed routes on the same crags when there have been plenty of others around and on ajoining routes - are only the former legitimate solo's?
You could argue yes, because whilst if you fall, it doesn't make any difference, the presence of others could be useful if you decide you need to bail and could therefore be rescued by them.
I think it changes when it comes to winter and alpine climbing. For me, this is where the big psychological factors come into play because of the increased objective dangers, often outside of our control, such as weather, avalanche, seracs, unstable terrain etc.
This is where there's a huge difference between climbing a route alone or with someone else - whether you're roped up or not.
So, whilst I'd happily claim a solo of Left Wall even if there were 6 other people soloing it at the same time, and the cast of Ben Hur on all the ajoining routes, I would only claim a winter/alpine solo if I was 'alone' on the route.
All of which means, I'm probably just as confused as others as to what the term solo really means when applied to the full range of climbing activity.
