I mean, 1 satoshi is not treated by almost all nodes as a 'proper' bitcoin transaction fee. The minimum non-zero fee used to be 0.0001 BTC per 1 kb.

DEFINITION of 'Required Minimum Distribution - RMD' A required minimum distribution (RMD) is the amount that traditional, SEP or SIMPLE IRA owners and qualified plan participants must begin distributing from their retirement accounts by April 1 following the year they reach age 70.5. RMD amounts must then be distributed each subsequent year based on the current RMD distribution calculation amounts. BREAKING DOWN 'Required Minimum Distribution - RMD' These required minimum distributions are determined Sat, 13 Jan 2018 13:25:00.

Minimum Transaction Fees Minimum transaction fees protect the CoinSpark system from denial-of-service attacks. If a bitcoin transaction has CoinSpark or metadata attached, that metadata is only considered valid if the transaction has a sufficient transaction fee, which is collected by the miner who included that transaction in a bitcoin block. There is no minimum fee required for metadata to be valid. Without minimum fees, CoinSpark would be vulnerable to an attack in which a user could create a large number of unspent bitcoin transaction outputs each of which contains a large number of different assets.

This would not cause a problem for services such as following the movements of an individual asset type over bitcoin transactions. However it would greatly inflate the storage requirements of any service attempting to track the movements of all CoinSpark assets.

CoinSpark’s minimum fee is calculated from the number of new asset outputs that a transaction might create multiplied by the lower of: (a) the quantity of bitcoin in the smallest non- OP_RETURN output of that transaction, and (b) 1000 satoshis. In this way, CoinSpark piggybacks on the anti-dust threshold introduced in Bitcoin 0.8.2, without being tied to a particular value of that threshold. If new versions of Bitcoin Core reduce this threshold (currently ~550 satoshis in Bitcoin 0.9), and so allow transactions with smaller outputs to be relayed by the default bitcoin client, CoinSpark’s minimum fees for new transactions can drop in tandem. If new versions of Bitcoin Core greatly increase this threshold, CoinSpark will still treat 1000 satoshis as an upper limit. In either case, the valid or invalid status of CoinSpark metadata on an old transaction is determined entirely by that transaction, independent of the current anti-dust threshold.

You can easily calculate the minimum transaction fee required for CoinSpark metadata to be valid using the appropriate for your programming language. Checking if genesis metadata has a sufficient fee.
