Workbook Broadcasting - Alternatives

Hello All,

We have a situation where we are seeing lot of issues reported for BEx Broadcasting as we are still using 3x worbooks and pre calc server.I did a lot of research on the alternatives on precal server but did not find any useful information except for upgrade. I need to know

- I understood if we do a technical upgrade to 7x then we get enhanced features but is there anything available in the market to replace Bex 7x Precalculation?

- What tool will be preferred if we move to HANA and need similar to workbook broadcasting?

Thanks
